A harmonic drive apparatus comprises a circular spline which has internal spline teeth and which is rotatable around a rotational axis , a flexible cylindrical flexspline which is concentrically disposed within the circular spline and which has external spline teeth , the number of flexspline external teeth being less than the number of internal ...
The crankshaft harmonic balancer is connected to the crankshaft, and absorbs many of the vibrations that the engine creates. The engine creates a large amount of force that is delivered to the crankshaft, which transfers the power to the transmission.he harmonic balancer (also called âcrank pulley damperâ), connected to the crankshaft of an engine, reduces engine vibration and serves as a pulley for the drive belts.
